Muslims living in the world's tallest tower will have to wait even longer to break their fast during the holy month of Ramadan.

Mohammed al-Qubaisi, Dubai's top cleric, said on Sunday that Burj Khalifa residents living above the 80th floor should wait two additional minutes to break their dawn-to-dusk fast while those above the 150th floor must wait three extra minutes because they will be able to see the sun longer than those on the ground.

The half-mile high tower has 160 habitable floors.

Al-Qubaisi said the decree is similar to those relating to Muslims travelling by air, and harkens back to a time when people living in the mountains broke their fast after those at lower elevations.
